Simple DB question

[adamboalt]

SELECT zip FROM cart
WHERE session = '$cart_id' AND
ValueA = 'y' or ValueB = 'y';

Is this proper?

I want the session to be a must and I want having one of the value a must - but both not required.

Thanks,

Adam

SELECT zip FROM cart 
WHERE session = '$cart_id' AND 
(ValueA = 'y' OR ValueB = 'y');

Hope this helps 😉
